Today’s first bottomless pit that will suck your life away is a simple looking problem that starts out easy and quickly gets aggravatingly difficult … The problem is called Planarity and requires you to rearrange a set of nodes so that the lines interconnecting them do not across each other. Written in Flash (whcih provides for much smoother operation than Java-based puzzles), Planarity is annoyingly addictive. The problems start at level 1 with six nodes and then go to level 2 with 8, level 3 with 16, and so on. All levels can be solved if you have enough time and the only reward is your score. Prepare for extended unproductiveness.
